Lakes Michigan and Huron (hydrologically one lake) are on course to have record water levels this month:
After late snowstorms and record-setting rainfall this spring, Lake Michigan’s water levels are projected to rise to a record level this month.
The rising water, which could swell more than 635 mm above its long-term monthly average, is expected to tie the previous June peak set in 1986.
May’s record-setting torrential rainfall was a catalyst for Lake Michigan’s surge in water levels, said Keith Kompoltowicz chief of watershed hydrology with the U.S. Army Corps of Engineers’ district office in Detroit.
The National Weather Service’s Chicago office on Friday tweeted that water levels already had hit a record — but the service was referring to a daily measurement, and the Army Corps only counts a full month’s average levels for record purposes.
Here's the official chart as of yesterday:
Meanwhile, Lake Ontario has broken its record already, and by a lot:
And all that fresh water just goes down the St Lawrence right into the Gulf Stream...
I had these lined up to read at lunchtime:
Meanwhile, for only the second time in four weeks, we can see sun outside the office windows:
In the month I've owned my Prius, I've driven 439 km and used 8.8 L of fuel. That's a fuel economy of 0.5 L/100 km. My old BMW got around 12 L/100 km, for comparison. Most of the time I don't even use gasoline, because she can run about 35 km on battery power, and I rarely drive farther than that in a day.
I also haven't named her yet—until now. I'm going with Hana (はな or 初夏), which means "early summer." Fitting for a car meant to help prevent global warming.
She's still this pretty:
Yesterday was a bit busy. I spent my morning getting this:
I haven't named it yet. Current thoughts are Hinata (一陽), Hana (初夏), and Asahi (旦陽). (The new car was built in Naguro, Japan; thus, a Japanese name.)
The new Prius replaces Magdalena (built in Munich), the BMW 335iX that I got in 2012. Poor Lena, she was so old and decrepit she just couldn't go on much longer. She was burning 13.9 L/100 km, which is just awful. The new car, so far, hasn't burned any gasoline at all—it's only run off batteries.
Then I photographed a wedding. Two of my friends got married in what they called a "rogue ceremony" at a public building in Chicago. It was intimate, fun, and exactly right. Now I just have to process 450 shots...by next week...
This afternoon, I'm flying to my Ancestral Homeland via Atlanta. Tomorrow, St. Paul's. So it'll be a busy week.
Update: We had about 10 minutes of sun this morning, so I got a better photo of the car:
It turns out, cemeteries provide really good observational data on climate change:
[T]he value of this greenspace has only grown as the communities around them have densified and urbanized — leaving cemeteries as unique nature preserves. In the case of Mount Auburn, people have consciously planted diverse trees, shrubs, and flowers from all over the world and cared for them tenderly over decades or even centuries. In other cases, though, plants that might otherwise be replaced by foreign varietals can thrive under a cemetery’s more passive management style, like the prairie cemeteries of Illinois, or even the woodsy outerboroughs of New York City.
At Mount Auburn [outside Boston], a team of interdisciplinary scientists now train volunteers in phenological data collection. In the spring, they look for things like bursting buds, insect onset, and the effect of shifting timescales on migratory birds. Later in the year, they monitor the duration of autumn. To ensure accuracy, the specific trees under observation are marked throughout the cemetery; this dogwood, that gingko. And all of this data is shared with the national network. “What we know is that plants are now flowering about two weeks earlier than they did in Thoreau’s time, and trees are also leafing out about two weeks earlier,” Boston University biology professor Richard Primack told local radio station WBUR. “And we know that birds are arriving a couple of days earlier than in Thoreau’s time.” What we learn next will come from the logs Mount Auburn’s team is making now.
Just an aside, I live in an 800-meter-wide neighborhood situated between two large cemeteries. They share a population of coyotes who frequently use the streets and alleys to move between them. This is the closer of the two:
No, we have not wiped out 60% of all animals, FFS:
Since Monday, news networks and social media have been abuzz with the claim that, as The Guardian among others tweeted, “humanity has wiped out 60 percent of animals since 1970”—a stark and staggering figure based on the latest iteration of the WWF’s Living Planet report.
But that isn’t really what the report showed.
Ultimately, they found that between 1970 and 2014, the size of vertebrate populations has declined by 60 percent on average. That is absolutely not the same as saying that humans have culled 60 percent of animals—a distinction that the report’s technical supplement explicitly states. “It is not a census of all wildlife but reports how wildlife populations have changed in size,” the authors write.
CityLab's article includes math, that turns out not to be difficult in the least.
The report is still alarming, of course. But not in the way some science reporters seem to believe.
Washington Post political reporter Philip Bump lays it out:
[T]he effects of the increased heat are much broader than simply higher temperatures. In an effort to delineate what scientists expect to see as the world warms, I spoke with Alex Halliday, director of the Earth Institute at Columbia University.
Direct effects of higher temperatures
Increased health risks. One of the most immediate effects of higher temperatures is an increased threat of health risks such as heat stroke. As noted above, this is probably the most easily understood risk.
Drought. There will be more droughts. For one thing, higher temperatures will lead to faster evaporation of surface water. For another, they will mean less snowfall, as precipitation will be more likely to fall as rain. In some regions, like much of the Southwest, flows of water through the spring and summer are a function of snow melting in the mountains. Reduced snowpack means less water later in the year.
Wildfires. Higher temperatures and drier conditions in some places will also help wildfires spread and lengthen the wildfire season overall.
It gets better from there. So its nice to know that the world's second-biggest emitter of greenhouse gases plans to reduce regulations to allow even more emissions.
The Cook County Forest Preserve District is building "bat condos:"
The 4-by-4-foot structures, which look like doghouses without doors or windows, rest atop 12-foot stilts and are big enough for as many as 2,000 bats, or, more specifically, bat mothers.
“These ‘bat condos’ are really bat maternity colonies,” said Margaret Frisbie, the Friends’ executive director. “You get a whole bunch of bats in there and then they help each other survive.”
Bats help control populations of mosquitoes and other insects, pollinate plants and disperse seeds that play an important role in the ecosystem.
Longtime readers may remember that a bat tried to move into my condo a few years ago:
Not only do the Great Lakes face threats from thirsty populations outside their basin, but they're also chock full of plastic microparticles:
One recent study found microplastic particles—fragments measuring less then 5 millimeters—in globally sourced tap water and beer brewed with water from the Great Lakes.
According to recent estimates, over 8 million tons of plastic enter the oceans every year. Using that study’s calculations of how much plastic pollution per person enters the water in coastal regions, one of us (Matthew Hoffman) has estimated that around 10,000 tons of plastic enter the Great Lakes annually. Now we are analyzing where it accumulates and how it may affect aquatic life.
Using our models, we created maps that predict the average surface distribution of Great Lakes plastic pollution. They show that most of it ends up closer to shore. This helps to explain why so much plastic is found on Great Lakes beaches: In 2017 alone, volunteers with the Alliance for the Great Lakes collected more than 16 tons of plastic at beach cleanups. If more plastic is ending up near shore, where more wildlife is located and where we obtain our drinking water, is that really a better outcome than a garbage patch?
Mmm. Plastic beer! Since most of the beer I drink comes from breweries walking distance from my house...yum!
After watching the Aral Sea disaster unfold in the second half of the last century, governors of the states and provinces around the Great Lakes formed a compact to prevent a similar problem in North America. Crain's looks at how well it's done for the past 10 years:
Hammered out over five years, the Compact, aimed at keeping Great Lakes water in the Great Lakes, was approved by the legislatures of all eight states bordering the Great Lakes, Congress and the Canadian provinces and signed into law by President George W. Bush on Oct. 3, 2008.
The Great Lakes Compact prohibits new or increased diversions outside the Great Lakes Basin with limited exceptions for communities and counties that straddle the basin boundary and meet rigorous standards. It asks states to develop water conservation plans, collect water use data, and produce annual water use reports. Great Lakes states as well as Ontario and Quebec are to keep track of impacts of water use in the basin.
Certainly, the future of water on the planet seems fraught enough to make one wonder how the Great Lake Compact will fare as the years pass. The most ardent supporters of the Compact say that challenges abound. These include a changing climate that is expected to bring drought as well as heightened political pressure to open up what some view as an invaluable public resource now off limits to the rest of the world.
So it is easy to see why the Great Lakes loom large in the eyes of those who seek to solve their water woes. The lakes are the largest system of fresh surface water on Earth. They hold 84 percent of North America's surface fresh water and about 21 percent of the world's supply, according to the U.S. Environmental Protection Agency.
This will be one to watch. Being adjacent to Lake Michigan is one of the biggest reasons I'm optimistic about Chicago; but what if the shoreline were 20 kilometers away? It could happen.
